The human ear is the special sensory receptor for the sound stimulus. The external ear begins with a funnel-like auricle. This auricle serves as a collector of the airborne waves and directs them into the external auditory meatus.

At the inner end of this passage, the waves act upon the tympanic membrane (eardrum). The external auditory meatus is protected by a special substance called earwax (cerumen).
The human body is composed of a series of linkages, block on top of block. These blocks can be arranged in a multitude of patterns called postures. Overall, we refer to this process as the general body sense. The internal ear provides one of the input systems for the general body sense.

Molecules of various materials are dispersed (spread) throughout the air we breathe. A special olfactory epithelium is located in the upper recesses of the nasal chambers in the head.

It passes through these nerves to the olfactory bulbs and then into the opposite cerebral hemisphere. Here, the information becomes the sensation of smell.
Organs known as taste buds are scattered over the tongue and the rear of the mouth. Special hair cells in the taste buds are chemoreceptors to react to these molecules.

The information received by the hair cells of the taste buds is transmitted to the opposite side of the brain by way of three cranial nerves. This information is interpreted by the cerebral hemispheres as the sensation of taste.
